Laser-based Micromanipulation of Biological Materials (G)
The Physics of the Actin Cytoskeleton (S)

Josef Käs is an assistant professor of physics at the Center for Nonlinear Dynamics and the Institute for Cellular and Molecular Biology at the University of Texas at Austin. He received his Ph.D. from the Technische UniversitÉt MÄnchen. His research involves the next big challenge for physics: studies of soft condensed matter physics on the scale of nanometers to tens of microns, i.e., on the scale of proteins and cells, in complex biological matter-often far from equilibrium and frequently behaving in a highly nonlinear manner. "There has been tremendous progress in molecular biology," Käs says. "Nevertheless, many of the questions addressed by molecular biology can only be understood by developing a novel combination of nanosciences and soft condensed matter physics." He says one of the most appealing aspects of this synergetic research in physics, chemistry and biology is that it simultaneously advances fundamental science and provides novel applications in biomedicine and materials sciences.

The Level Structure of Matter (G)
Bouchet and Imes: First African American Physicists (P,G)
Models of Periodic Diseases: A "Big Bang" Vaccination Strategy (G, S)

Ronald E. Mickens is the Distinguished Fuller E. Callaway Professor of Physics at Clark Atlanta University. He received his Ph.D. in theoretical physics from Vanderbilt University and has held postdoctoral positions at the Center for Theoretical Physics-MIT, The Joint Institute for Laboratory Astrophysics, and Vanderbilt University. His current research interests include nonlinear oscillations, difference equations, numerical integration of differential equations using nonstandard finite difference schemes, mathematical modeling of periodic diseases, and the history/sociology of African Americans in science. He has published more than 200 research papers, written five books, and edited five volumes. Professor Mickens serves on the editorial boards of several research journals including the Journal of Difference Equations and Applications. His professional memberships include AAAS, the American Mathematical Society, the American Physical Society, the National Society of Black Physicists (for which he is an elected fellow), and the Society for Mathematical Biology.

The Level Structure of Matter (G)
Since is possible because the various phenomena of the physical universe, to a very good approximation, can be compartmentalized. Thus, phenomena in a given compartment can be studied essentially independently of those in other compartments. These compartments are generally conceptual in nature and are associated with particular space and time scales. The main purpose of this lecture is to indicate how the important properties of various levels arise from the four basic interactions: gravity, electromagnetism, weak, and nuclear. Extensive application of elementary dimensional analysis is used to obtain these results.

Bouchet and Imes: First African American Physicists (P,G)
The first African American to receive the Ph.D. in any field was Edward Bouchet in 1876 (Yale University, Physics). This lecture presents the life and career of Bouchet and the world recognized research of Elmer Imes (Ph.D. in Physics, University of Michigan, 1918) on the spectroscopy of diatomic molecules. A general discussion of the African American "presence in science" will also be provided.

A 'Big Bang' Vaccination Strategy (G,S)
In a recent paper, Shulgin et al. [1] constructed a mathematical model to study a "pulse" vaccination strategy for the eradication of measles. They formulate their work within the framework of a continuous SIR epidemic model. They demonstrate theoretically, under various assumptions, that pulse vaccination can lead to eradication of measles epidemics. We examine some of these same issues within the framework of a discrete model based on the work of Anderson and May [2,3].

This research is supported by grants from DOE and the MBRS-SCORE Program at Clark Atlanta University.

Spectroscopy and Imaging of Tissues with Diffusing Light (G)
Entropy in Suspension (G)

Arjun Yodh is the James M. Skinner Professor of Science at the University of Pennsylvania. Physics and Astronomy is his home department, and he has a secondary appointment in the Department of Radiation Oncology in the Medical School. He received his Ph.D. from Harvard University and his BSc. from Cornell University. His current interests span fundamental and applied questions in condensed matter physics, medical and biophysics, and the optical sciences. He has devised microscopic methods to measure tiny forces on macromolecules in suspension, and in studies of solution entropy, he has identified novel ways to control the self-assembly of macromolecules. His group has made important contributions to an interdisciplinary field of optical research aiming to understand and use diffuse light to probe highly scattering materials, from complex fluids to human tissues. Lastly, he has pioneered the use of nonlinear optics to probe level structure, charge dynamics, and defects at the interface between crystalline solids. His lab group has several areas of ongoing research including: complex fluids, laser spectroscopy and micromanipulation, biomedical optics, and nonlinear optics. Professor Yodh was a National Science Foundation Presidential Young Investigator (1990-95), an Alfred P. Sloan Research Fellow (1991-94), and an Office of Naval Research Navy Young Investigator (1991-94). He is a Fellow of the Optical Society of America and the American Physical Society, and has most recently held the William Smith Term Professorship of Physics & Astronomy at Penn.

Spectroscopy and Imaging of Tissues with Diffusing Light (G)
Optical methods offer a range of spectroscopies useful for characterization of a wide variety of samples. The optical spectroscopies are rigorous, and work well in simple, homogenous, optically thin samples. Unfortunately many practical materials are not so simple. Human tissues, for example, are highly scattering media. Light penetration in tissues is limited, and generally the effects of tissue absorption and internal motion must be separated from the effects of tissue scattering. Nevertheless, the use of light to investigate the human body interior has grown enormously in recent years, in part as a result in advances in our fundamental understanding about light transport in highly scattering materials, and in part as a result of technological innovations in optics. Arguably the most critical advance in the field has been the recognition and widespread acceptance that light transport over long distances in tissues is well approximated as a diffusive process. Waves of diffuse light energy density propagate deeply in tissues and obey simple rules such as refraction, diffraction, interference, and dispersion as they encounter variations in tissue optical properties. I will discuss these basic phenomena and touch on recent physiological applications of diffuse light imaging and spectroscopy including functional imaging brain, and diffuse optical mammography.

Entropy in Suspension (G)

The addition of small macromolecules to a suspension of large particles causes an entropic attraction to arise between the large particles. The origin of this attractive force is the increase in free volume (i.e. entropy) available to the smaller particles that arises when the large particles are moved close together. We review this simple thermodynamic effect and experimentally explore its manifestations. Light forces (i.e. optical tweezers) are used to measure these interactions, and entropically driven nucleation and assembly of colloidal crystals is discussed and demonstrated.
